Onofrio's investigation led to the search of the bedroom of Chaz Yopp at 75 George St.

As officers attempted to search Yopp's bedroom, Brit Martin blocked the entry, Smith said. Martin allegedly pushed an officer, and was arrested after a brief struggle.

During the bedroom search, police found 146.9 grams of marijuana, a .38-caliber revolver and drug paraphernalia.

Yopp, 18, was charged with possession of a pistol without a permit, possession of narcotics, possession of marijuana, possession of marijuana with the intent to sell, operating a drug factory and possession of drug paraphernalia.

Martin, 28, of 245 Alston Ave., New Haven, was charged with interfering with an investigation.
